CHICAGO, ILLINOIS, A CORPORATION OF DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 743,278, dated November 3, 1903.

Application led December 18l 19072. Serial No. 135,711. (No model.) i

To all whom t may concern:

Beit known that I, HARRY STILLsoN HART, i

a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to that class of cars which are used for the purpose of carryingl freight that may be dumped through the bottom portion thereof, and particularly to that class which have bottom portions for thedumping of the freight between the trucks and rails of the track, all of which will more fully hereinafter appear.

The principal object of this invention is to provide a simple, economical, and efficient lun11p-car-one that will carry the maximum Further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists principally in a dumping-car in which there are combined a supporting-framework having upwardly-extending side and end boards and a bottom portion formed in three parts, two parts im'- movably fixed in fiat planes and located drectly over the car-trucks at each end of the car, and a V-shaped dumping hopper portion at the center and between the car-trucks only. The invention consists, further and finally, in the combination, arrangements, and details thereof as set forth in the following description and claims.

In the accompanying drawings, Figure 1 `is a longitudinal sectional elevation of a cary constructed in accordance with these improvements, taken on line 1 of Fig. 2 looking Vin the direction of the arrow; Fig. 2, a plan yiew of the same looking at it from above;

Fig. 3, an enlarged cross-sectional elevation taken on line 3 of Fig. l looking in the direction of the arrow, and Fig. 4 a similar view taken on line 4 of Fig. l looking in the direction of the arrow.

In the art to which this invention relates it is well known that it is highly desirable to have a car which is adapted to carry dierent kinds of freight that can he dumped through the bottom portion and that some kinds of such freight are heavier than others. As a consequence, it is desirable to have a car which has a maximum carrying capacity-one that will carry in bulk form all the load that it is necessary to carry in this type of car.

The principal object of this invention, therefore, is to provide a dump-car which will embody the above-noted as well as other advantages, all of which will more fully hereinafter appear.

In illustrating and describing these improvements I have only shown and described that which I consider to be new, taken in connection with so much as is old as will properly disclose the invention to others and enable those skilled in the art to practice the same, leaving out of consideration other and well-known mechanisms which if set forth herein would only tend to confusion, prolixity, and ambiguity.

In constructing a car in accordance with these improvements a supporting-frame is provided formed of side sills a, intermediate sills h, center sills c, end sills d, and other well-known members, asshown in the draw ings, but which, as they form no material part of the invention, need no' further consideration. Thissupporting-framework is provided with upwardlyfextending side boards e and end boards f, secured thereto and held in operative position in any well-known and usual manner. i

It is highly desirable to have the ear so arrangedthat it may have all the capacity of a gondola car and the efficiency of a hopperbottom dumping-car. In order to accomplish these results, a bottom portion is provided and formed in three parts-two relatively fixed or immovable parts g, laid iu iiat planes at the ordinary door-level at each end of the car and directly over the car-trucks, andthe third part formed in the shape ofa V-shaped hopper h, arranged between the trucks only, with its apex t' at or near the longitudinal center of the car. One of the inclinedportions or walls of the hopper extends downward only to the bottom of the transverse sills and is provided with a dumping-door j, pivotally attached to such sills and adapted to be raised and lowered by means of the chain IOO k and rock-shaft Z. The other inclined wall of the hopper extends downward from the perpendicular side wall of the car between the longitudinal bottom sills of the framework and between and downward beyond the transverse sills to the apex or center of the hopper and is fixed and rigid throughout.

The liat bottom portions, as above suggested, extend entirely over the car-trucks m and are relatively immovable or fixed to the car-frame, so that no material can be dumped onto the car-trucks. The inclined sides or walls which forni the hopper-bottom extend upwardly and outwardly to a point considerably above the fioor-level, where they meet the side boards of the car.

The principal advantages incident to the use of a car constructed in accordance with these improvements are, first, a larger carrying capacity than usual is provided; second, the advantages of a d umping-car are obtained, and,third, the car can be loaded either over the trucks or between the same whenever necessary or desirable.

I claiml. In acar of the class described, the combination of a supporting-framework comprising longitudinal and transverse sills having permanent upwardly-extending side and end boards, a bottom formed of flat portions over the car-trucks at each end and a relatively fixed V-shaped dumping hopper portion at the center and between the car-trucks with its apex arranged at or near the longitudinal center of the car comprising two inclined side walls one of which extends downward between and beyond the longitudinal and transverse sills in fixed and rigid relation thereto, to the center and bottom of such hopper, and end walls for such hopper extending upward to but not beyond the fiat floor portions leaving the ends of the hopper open above the level of the fiat portion of the floor, substantially as described.

2. In a car of the class described, the combination of a supporting-framework comprising longitudinal and transverse sills provided with permanent upwardly-extending side and end portions, a bottom portion formed of relatively immovable iiat portions arranged over the car-trucks and a relatively fixed or irninovable V-shaped dumping hopper portion at the center extending between the trucks only with its apex arranged at or near the -longitudinal center of the car comprising two inclined side walls one of which extends downward between and beyond the longitudinal and transverse sills in fixed rigid relation thereto, to the center and bottom of such hopper, and end walls for such hopper extending upward to but not beyond the fiat floor portions leaving the ends of the hopper open above the level of the fiat portion of the floor, substantially as described.

3. In a car of the class described, the combination of a supporting-frame comprising longitudinal and transverse sills provided with upwardly-extending side and end boards, abottom portion formed in three parts,two fiat portions relatively immovably fixed at each end at or near the ordinary floor-level and extending entirely over the cartrucksa V- shaped dumping hopper port-ion at the center between the car-trucks only and with its apex arranged at the longitudinal center of the car comprising inclined side walls relatively fixed and extending above the Hoor-level to meet the side boards of the car, one of which side walls extends downward between and beyond the longitudinal and transverse sills to the longitudinal center of the car and forms one side of the apex of the hopper, and end walls for such hopper extending upward to-but not beyond the flat floor portions leaving the ends of the hopper open above the level ofthe flat portion of the l'loor and adumping-door in the opposite inclined hopper bottom portion extending downward into engagement with the lower edge of such rigid hopper-wall, and pivotally connected to the sills, substantially as described.

4. In a car of the class described, the combination of a supporting-framework comprising'side and end sills, a bottom comprising at portions extending over the car-trucks at each end, a hopper portion having inclined side walls extending upward beyond the fiat portion of the fioor, and having end walls extending upward to but not beyond such fiat Hoor portions leaving the ends of the hopper open above the level of the fia-t portions of the door, and perpendicular side and end walls extending upward from the fiat portion of the floor at the outer edges thereof, substantially as described.

5. In a car of the class described, the combination of a supporting-framework comprising side and end sills, a bottom comprising fiat end portions extending over and resting upon such sills, a hopper portion having inclined side walls extending upward beyond the fiat portion of the floor, and having end walls extending upward to but not beyond such flat floor portions leaving the ends of the hopper open above the level of the fiat portions of the floor, and upright side and end walls extending upward from the fiat portion ofthe floor at the outer edges thereof and above the upper edge of the inclined side walls of the hopper portion, substantially as described.

6. In a car ofthe class described, the combination of a supporting-framework comprising transverse and longitudinal sills, a bottom comprising fiat end portions extending over such transverse and longitudinal sills and resting thereon, a relatively fixed central hopper portion having inclined walls extending upward beyond the floor-level and downward between the longitudinal sills, and having end Walls extending upward to but not beyond such fiat floor portions leaving the ends of the hopper openpabove the level of the flat portions of the floor, and upright side IOO IIO

v and end wallsextending upward from the floor-level at the outer edges of the fiat portions of the loor and above the upper edges of the side walls of such hopper portion, substantially as described.
